If you could emigrate to Mars, but could never come back to Earth, would you go?

I just realised that earth doesn't rise as seen from moon since moon tidally locked to earth.



**** it. Let's build that supercollider.

Yes i think making small pockets of comfortable domed enviroments will be the practical(!) way to go. I imagine that the huge amount of economic effort to make it work would rule out it becoming a socialist paradise, unfortunately.
It would have to be an even more capitalist venture than what we see on earth today - which might have its advantages; as maybe it would persude all the most ruthless money orientated individuals to go off-world and then we would get the space and time to actually save our one and only habitable planet, before its too late and all the trees are gone/sea's poisonous/air polluted/animals dead etc.

So i'm for colonising the planets we can and shiping the A**holes to make their fortunes, it might be our only hope of long term survival

You see? Everbody's happier this way!

[Bosh]

Just imagine how bad the beer would be there though.
What ever they'll have to drink there has GOT to be better than soju.

You'll drink your synthale and you'll like it, citizen!!!

Hmph.

One

Three

?

[The Mad Monk]

There's a perfectly reasonable explanation for that.

[KrazyHorse]

It wobbles. Only a very small segment of the longitudes of the moon will experience earthrise (IIRC something like 5%)

[Skanky Burns]

How long until the Earth is tidally locked to the moon?

[KrazyHorse]

IIRC 1.5 billion years.

[KrazyHorse]

The angular momentum of the Earth will be transferred to orbital velocity of the earth-moon pair.

This will increase the earth-moon distance to the point where rotation has period of ~50 days as opposed to 28 (again, IIRC)

[The Mad Monk]

While the moon is tidally locked, and the moon's rotational period is equal to the orbital period, it must be noted that it's orbital speed within any given period is not constant, due to fact that the orbit is elliptical - it speeds up as it nears Earth, and slows down as it recedes from Earth.

As such, the moon appears rotate ever so slightly back - and - forth each month.

[The Mad Monk]

But then, Kitty just told you that.

[KrazyHorse]

You gave fuller explanation.

[Skanky Burns]

Good work, both.
